74ALVC162245
Low Voltage 16-Bit Bidirectional Transceiver
with 3.6V Tolerant Inputs and Outputs
and 26
Ω
Series Resistors in A Port Outputs
General Description
The ALVC162245 contains sixteen non-inverting bidirec-
tional buffers with 3-STATE outputs and is intended for bus
oriented applications. The device is byte controlled. Each
byte has separate 3-STATE control inputs which can be
shorted together for full 16-bit operation. The T/R inputs
determine the direction of data flow through the device.
The OE inputs disable both the A and B Ports by placing
them in a high impedance state.
The 74ALVC162245 is designed for low voltage (1.65V to
3.6V) V
CC
applications with I/O compatibility up to 3.6V.
The 74ALVC162245 is also designed with 26
Ω
series
resistance in the A Port outputs. This design reduces line
noise in applications such as memory address drivers,
clock drivers, and bus transceivers/transmitters.
The 74ALVC162245 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.

Note 1:
To ensure the high-impedance state during power up or power
down, OE should be tied to V

through a pull-up resistor; the minimum
value of the resistor is determined by the current-sourcing capability of the
driver.

Note 2:
The Absolute Maximum Ratings are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the Absolute Maximum Rat-
ings. The “Recommended Operating Conditions” table will define the condi-
tions for actual device operation.
